Parks' attorney, James Gust, requested the exam, which a Michigan State Police detective will conduct, to show that Parks didn't intentionally bring the gun into the building, which houses 12 courtrooms and numerous county offices, including the prosecutor's office.

Parks already has passed a private polygraph test in which she said “that she didn't know the gun was in her purse and that she didn't intentionally bring it into the courthouse,” Gust said.

Polygraph results are not admissible in court, but prosecutors can use the results in determining possible resolutions to cases, such as dismissals or plea agreements.

She was entering the building to pay a ticket for parking on a lawn, Gust said, and had “no intent” to bring the gun into the building, which houses 12 courtrooms and numerous county offices, including the prosecutor's office.

Sheriff's Lt. Randy Pfau has said deputies determined that the gun was not registered to the woman but was not stolen.

Saginaw County District Judge Kyle Higgs Tarrant, who arraigned Parks, said Parks was in possession of a bottle of Vicodin that was prescribed to somebody else.

Borchard said Thursday that if the polygraph test is not completed by Parks' next scheduled trial date that the trial will begin without it.
